libext2fs: unix_io: fix_potential error path deadlock in flush_cached_blocks()

We can't call the error handler while holding the CACHE_MUTEX (see
previous commit, "libext2fs: unix_io: fix_potential error path
deadlock in reuse_cache()" for details), so first try to write out all
of the dirty blocks in the cache, and then for those where we had
errors, then call the error handler.
